GENUS AND SPECIES

Phalaenopsis Blume

VARIETY DENOMINATION

‘PHALDESXEN’

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar ofPhalaenopsis plant, botanically known as Phalaenopsis of the Orchidaceaefamily, and hereinafter referred to by the cultivar name ‘PHALDESXEN’.

Phalaenopsis comprises a genus of about 60 species of herbaceousperennials many of which, or the hybrids thereof, are suitable forcultivar in the home or greenhouse. Phalaenopsis is predominantlyepiphytic or rock dwelling, and is native to tropical Asia, the MalayArchipelago, and Oceania. The species typically has 2-ranked, fleshy,oblong or elliptic leaves affixed to a short central stem (monopodialgrowth), which vary in size from 12 to 20 cm to over 60 cm. The leavesmay be entirely green or mottled with silver grey.

Phalaenopsis orchids, often referred to as ‘Moth Orchids’ in thehorticultural trade, are frequently used to furnish cut flowers for theflorist trade or sold as flowering potted-plants for home orinteriorscape.

Phalaenopsis produces upright or pendent lateral racemes or panicle,often with many showy flowers which open in succession beginning withthe lowermost. The flowers possess three sepals and three petals; thelateral ones being alike. The lowermost petals, called the labellum, isthree-lobed and is often more brightly-colored than the other flowersegments. Flower colors include various shades of pink, white, yellow,and red-brown.

Phalaenopsis orchids are typically propagated from seeds. Asexualpropagation of Phalaenopsis is often done from off-shoots which arisefrom the lower bracts of the inflorescence. The resulting plants aredetached from the mother plants and may be planted in a suitablesubstrate.

The new Phalaenopsis ‘PHALDESXEN’ is particularly characterized by itsattractive and unique purple-lilac flowers, economical propagation bytissue culture, rapid growth, and a plant dimension suitable forpackaging and shipping to the market.

‘PHALDESXEN’ is a product of a planned breeding program conducted inBleiswijk, The Netherlands.

The new Phalaenopsis ‘PHALDESXEN’ originated from a cross made in May2005 in Bleiswijk, The Netherlands. The female parent is a cream spottedPhalaenopsis pot plant named ‘01-5017’ (unpatented), while the maleparent is a purple Phalaenopsis pot plant named ‘22791-0004’(unpatented). A single plant was selected in January 2008 and has beenasexually reproduced repeatedly by tissue culture in Bleiswijk, TheNetherlands over a 3-year period. The new variety has been found toretain its distinctive characteristics through successive asexualpropagations.

Asexual reproduction of ‘PHALDESXEN’ by tissue culture was firstperformed in June 2011 in Bleiswijk, The Netherlands and hasdemonstrated that the new cultivar is firmly fixed and retained throughsuccessive generations of asexual reproduction.

Plant Breeder's Rights for this variety have been applied for in Europeon Apr. 25, 2014. ‘PHALDESXEN’ has not been made publicly available orsold anywhere in the world more than one year prior to the filing dateof this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishingcharacteristics of this new cultivar when grown under normalhorticultural practices in Bleiswijk, The Netherlands.

1) Purple-lilac spotted flowers that are a little bit striped;

2) 2 peduncles;

3) Inflorescence is long and moderate;

4) The shape of the leaf is oblong; and

5) Plants are propagated by tissue culture.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctivecharacteristics of ‘PHALDESXEN’. The data which define thesecharacteristics were collected from asexual reproductions carried out inBleiswijk, The Netherlands. The plant history was taken on 50-week oldplants which were planted from tissue culture in 12 centimeter pots andgrown in a greenhouse between 27° C. to 29° C. for 30 weeks, continuedby a cooling period of 8 weeks between 18° C. to 20° C. and 12 weeks ina greenhouse of 21° C. Observations were made in March 2014. Colorreadings were taken under 4-6000 lux natural light in the greenhouse.Color references are primarily to The R.H.S. Colour Chart of The RoyalHorticultural Society of London (R.H.S.) (2001).

‘PHALDESXEN’ differs from male parent ‘01-5017’ (unpatented) in that‘PHALDESXEN’ has an oblong shaped leaf, whereas ‘01-5017’ has alanceolate shaped leaf Additionally, ‘PHALDESXEN’ has a dark purplecallus of the lip and the pattern of the flower is spotted and a littlebit striped, whereas ‘01-5017’ has a yellow dotted callus of the lip andthe pattern of the flower is edged.

‘PHALDESXEN’ differs from commercial variety ‘PHALEQEF’ (unpatented) inthat ‘PHALDESXEN’ has a lateral lobe that is type IV, whereas ‘PHALEQEF’has a lateral lobe that is type V. Additionally, ‘PHALDESXEN’ has a darkpurple callus and a flower color that is purple-lilac spotted and alittle bit striped, whereas ‘PHALEQEF’ has a yellow callus and a flowercolor that is even purple.

I claim:
 1. A new and distinct variety of Phalaenopsis plant named‘PHALDESXEN’ as shown and described herein.
